Sadie Robertson is really just too cute—and chatting backstage with papa Willie Robertson and Uncle Si, we see where she gets her charm from.

The 16-year-old Duck Dynasty star made her New York Fashion Week debut on Monday, walking the runway at the Evening By Sherri Hill Spring 2014 show at Trump Tower.

Hill dressed the aspiring model in a black and white prom gown with a full-length, polka-dot skirt and a sleeveless sequined bodice topped off with sheer material.

Sadie admitted to E! News backstage before showtime that she was "a little nervous—but more excited than anything."

"I've done small [fashion-related] things in Louisiana, but this is New York Fashion Week," she said. "This is a whole new ball game!"

Indeed it was, and not just for her!

Sadie's great-uncle, Si Robertson, also told us backstage that this was definitely his first-ever fashion show—"and it'll probably be the last," he laughed.

And though Sadie's Sherri Hill prom dress will be the envy of any girl from any corner of the U.S., it had to get a very particular seal of approval before she could show it off in front of hundreds of people (and ultimately the entire Internet).

The dresses Sadie models are, of course, "daddy-approved," dad Willie assured us. "They have to make it once by me to make sure I give 'em the thumbs-up."

So, with that squared away, we now declare it open season on modeling offers for Sadie!

Be sure to watch the clip to see what Si has to say about beard-growing—and what he thinks of E! correspondent Robbie Laughlin's own attempt at facial hair—and tune into E! News weekdays at 7 p.m. & 11:30 p.m. for more coverage of New York Fashion Week.
